These devices come with easy-to-use image acquisition driver software. Unlike multimedia “frame grabbers”, the NI 1411 Series features increased image processing throughput, such as on-the-fly color conversion to HSL and partial image acquisition with programmable region of interest. Real-Time Color Conversion Real-time color conversion is especially useful for high-speed color matching in industrial or scientific applications, even in varying illumination. An example of HSL in action is using color to inspect the presence of an object even though there are shadows and/or reflections. Lighting variations do not affect the image (hue). Use the powerful color matching functions in IMAQ Vision to locate objects quickly and accurately with the onboard HSL conversion. Easy-to-Use Driver Software National Instruments NI-IMAQ driver level software offers the most comprehensive software interface for image acquisition. NI 1411 Series devices are shipped with the NI-IMAQ image acquisition driver software and National Instruments Measurement & Automation Explorer for easy configuration of NTSC and PAL color cameras. Using NI-IMAQ, you can quickly and easily start your application without having to program at the register level. You can program your image acquisition application in LabVIEW, LabWindows/CVI, and Measurement Studio. In addition, NI-IMAQ controls the NI 1411 digital I/O line. Performance Gains with Partial Image Acquisition The NI 1411 Series includes features that improve overall image acquisition and image processing speed. You can choose to acquire only a portion of the image using the onboard programmable ROI feature. You can configure the size of the acquired image using Measurement & Automation Explorer, or use the ROI tools in the NI-IMAQ driver software to transfer only a subset of the image to PC memory for processing. Partial image scanning results in fewer pixels to process. For example, using partial image scanning, you can reduce a 640 by 480 image to a 400 by 400 image and increase your processing speed by operating on 48 percent fewer pixels. Color Image Acquisition Performance Gains with Onboard Decimation Onboard decimation also provides image acquisition and processing performance gains by allowing onboard scaling or decimating of the image without using the PC processor. Onboard decimation scales the image by removing every second, fourth, or eighth pixel (powers of two only). By reducing the number of pixels (decimation) on the IMAQ board, the system has fewer pixels to process with the PC processor. If you remove every other pixel using onboard decimation, the image size decreases by 50 percent, which speeds up your processing. • Color or monochrome acquisition •1 NTSC, PAL, S-Video, RS-170, or CCIR input • Onboard real-time HSL color conversion for fast color matching • Partial image acquisition with onboard programmable region of interest • Onboard pixel decimation •Programmable gain and offset •3 by 8-bit RGB look-up table •1 external trigger/digital I/O line •Transfer rates up to 132 Mbytes/s Models • NI PCI-1411 • NI PXI-1411 Operating Systems •Windows 2000/NT/XP/Me/9x Recommended Software • LabVIEW • Measurement Studio •Vision Development Module - IMAQ Vision - NI Vision Builder Other Compatible Software • C/C++ Driver Software (included) • NI-IMAQ NI 1411 Single-Channel Color or Monochrome Image Acquisition INFO CODES For more information, or to order products online visit ni.com/info and enter: pci1411 pxi1411 BUY ONLINE! 596-597 Single Channel Color 11/11/02 4:31 PM Page 596 |
